Anyone clicking on the link will be treated to a remarkable image of the Horsehead and Flame Nebulae, next to the belt-edge star Alnitak in the constellation Orion the Hunter. With the kind reproduction permissions from Andrew Chatman of ASRAS, I’ve included the hi-res version of the image (lonked in the caption above) for your downloading and desktop-background-ing pleasure.
The Quadrantids turned out to be a wash for CNY, but we’ve had a few crystal clear nights near the New Moon for planetary and other observing. With, perhaps, a last major focus on Orion this year, a How-To seeking guide for nearby constellations using Orion was included in the article (reproduced below with caption).
I lament the lack of any mention of the Orionid Meteor Shower, which won’t be impressive anyway thanks to the Moon, but should still have been included for monthly completeness. What would have been included in the article is provided below:
Meteor showers are the result of the Earth passing through the debris field of a comet or asteroid. As these objects approach the warming sun in their long orbits, they leave tiny bits behind – imagine pebbles popping out the back of a large gravel truck on an increasingly bumpy road. In the case of meteor showers, the brilliant streaks you see are due to particles no larger than grains of sand. The Earth plows through the swarm of these tiny particles at up-to 12 miles-per-second. High in the upper atmosphere, these particles burn up due to friction and ionize the air around them, producing the long light trails we see. We can predict the peak observing nights for a meteor shower because we know when and where in Earth’s orbit we’ll pass through the same part of the Solar System – this yearly periodicity in meteor activity is what let us identity and name meteor showers well before we ever had evidence of what caused them.
The name of each meteor shower is based on the constellation from which the shooting stars appear to radiate – a position in the sky we call the radiant. In the case of the Orionids, the meteor shower radiant appears to be to the north/above of the belt and left shoulder of Orion, which rises from the east after 11 p.m. this month. The meteor shower itself is provided to us by Halley’s Comet, and is the best of the meteor showers associated with Halley’s debris field.
How to observe: Sadly, the Moon will be prominent in the late-night/early-morning sky during the days around the Orionid peak, making for a far less impressive display. The Orionids are not known for their impressive counts either, with 10 to 20 meteors per hour expected.
Orion marks the position of the meteor shower radiant, meaning the meteors themselves will seem to shoot roughly from the east to the west. To optimize your experience, lie flat on the ground with your feet pointed east and your head elevated – meteors will then appear to fly right over and around you. Counts and brightness tend to increase the later you stay out, with peak observing times usually between midnight and 4 a.m. The swarm of tiny particles is distributed broadly in orbit, meaning some people may shooting stars associated with the Orionids anytime this month.
Also, kudos to friend and fellow space trucker Prof. John McMahon for one orientational catch – the following:
Starting around mid-October, Jupiter will peak above the Western horizon just after 6:30 a.m.
Starting around mid-October, Jupiter will peak above the Eastern horizon just after 6:30 a.m.

For interested parties, this article also marks the second (and final) official mention (to the best of my knowledge) of our upcoming MOST/TACNY/CNYO hosting of International Observe The Moon Night on Saturday, October 8th. At present, the weather is looking less-than promising for even lunar observing, but plans are underway to handle the crowd either way.
If it rains Saturday night, then I recommend the following:
For interested parties, this article also marks the first official mention (to the best of my knowledge) of our upcoming MOST/TACNY/CNYO hosting of International Observe The Moon Night on Saturday, October 8th. Additional details to follow, but expect the observing to happen somewhere around The MOST itself.
Extra-special thanks to Nick Lamendola from the Astronomy Section of the Rochester Academy of Science (image above, taken from the grounds of my new observing stomping grounds at the Farash Center – click for a larger view) for the use of his Perseid composite as the article opener (one of the benefits of being a member of several local clubs is the listserve content – and the many fantastic images that fly by on a weekly basis).
In the interest of aggregation, quick post linking the first two in a new series of astronomy articles on newyorkupstate.com and syracuse.com. There’s an old adage in academia – “You don’t really know something until you can teach it.” To that end, these articles and their associated research prep are great fun and yet another excellent excuse to go out at night and compare the planetarium apps to the real thing (for which both Starry Night Pro and Stellarium are excellent organizational proxies. I’m currently leaning on Stellarium for the imagery because others who might get bit by the astronomy bug can download it for free and follow along. That said, Starry Night Pro is still my workhorse for fine detail as Stellarium continues to develop).
When the article series was first proposed, the goal for the Syracuse Media Group folks was to provide people in upstate some basic information for what was up and about in the night sky – when you step outside, what’s there to find? My hope is to provide the non-observer and novice observer just enough information to whet the appetite, hopefully coaxing readers to take some quality looks and, if all goes well, to seek out their local astronomy club for some serious observing – and learning.
Night sky-gazing in Upstate NY: What to look for in July
The series started just in time to highlight the Perseid Meteor Shower (and get its first linking to thanks to Glenn Coin’sarticle as we approached the Perseid peak), then August was chock full of interesting planetary events. The August article was also a first exposure to the issues of episodic astronomy – how to be as minimally referential as possible in any single article to previous articles (which is not easy given how much the search for constellations historically has involved the finding of a bright one to orient observers to a dimmer one).
July hit 78 shares on newyorkupstate.com, August hit 4400 – at that rate, the whole world will see the October article.
